HyperFrames is an open-source TypeScript framework, published under HeyGen's GitHub organization. It turns HTML, CSS, media and seekable animations into MP4 videos, and the project describes the output as deterministic. You can use it from a command-line tool, from coding agents such as Claude Code, Codex and Cursor through installable skills, or as the rendering engine behind hosted tools. It ships nine skills and about 450 ready-made blocks. It is Apache-2.0 licensed and needs Node.js 22+ and FFmpeg. Some features depend on HeyGen's Pro plan, and the README excerpt publishes no performance or fidelity figures.
